This sounds like very much like a full-blown ActiveX control. It should 
certainly be reasonable  to add supoport for DirectShow interfaces (like any COM
interfaces). How would it be registered? As well as being an ActiveX control, in
DirectShow it could qualify as both a transform filter, and as a source filter.

Re a GUI: I think it would need to support a property page - or several.
